What about if you are maxed and about to push out. You will have (generally) a rising mineral and gas count. Would it be viable at all?
If you're maxed, they're proberbly maxed too. When you're maxed, you end up pooling larva anyway, So you're basically trading the ability to remax as soon as your army dies for your opponants ability to create units about a minute later (Depends how much larva he has around). Keep in mind as well that even though you've stopped production, in the long term you've spent money that only delays the spending of his money. He still has that 600 gas to invest into Tech or Upgrades regardless if he can make units or not which is bad in the long run for you.
Call me crazy, but the only way I can think of this working is with perhaps a baneling drop onto the larva to clear it all away at the same time, but I think that's simply going a bit far, and if you spend your APM doing this, you risk losing the actual battle, which negates your entire plan.
